最近偶然发现了一篇总结css reset 的文章，拿出来给大家一起分享。
最近看到一个词叫css reset。什么叫做css reset呢？我理解为重置css，也就是重置默认样式。我在HTML下的默认样式中讲到，一些标签元素在HTML下有一个默认属性值，我们在写css页面的时候，为了避免在css中重复定义它们，我们需要重置默认样式（cssreset）。
CssReset也就Reset Css ,就是重置一些标签样式，或者说默认的样式。前端开发工作中有一款好的、统一的CssReset将提高开发效率，提高样式代码的重用，减少重复代码，减少维护成本。

在《超越css》 一书中建议我们做网站开始重置所有默认样式：
/* Normalizes margin,padding */
body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,p,blockquote,th,td{ margin:0;padding:0}
/* Normalizes font-size for headers */
h1,h2,h3,h4,h5,h6 { font-size:100%}
/* Removes list-style from lists */
ol,ul { list-style:none }
/* Normalizes font-size and font-weight to normal */
address,caption,cite,code,dfn,em,strong,th,var { font-size:normal;font-weight:normal }
/* Removes list-style from lists */
table { border-collapse:collapse; border-spacing:0 }
/* Removes border from fieldset and img */
fieldset,img { border:0 }
/* Left-aligns text in caption and th */
caption,th { text-align:left }
/* Removes quotation marks from q */
q:before,q:after { content:''}
那我们实际写代码的时候该怎么来css reset呢？
我个人推荐使用（Eric Meyer 和YUI ）的 css reset
